Traction Issues

I will unclamp the rear segments and try it out next spring when the track is warmer.
The engine has 9.65:1 compression, heads have bowls and runners cleaned up, intake and heads are gasket matched, 4425992 purple cam, 750 Edelbrock and TTI headers.
I was hoping to run 12.5 to 12.6 with this combo. I do not have subframe connectors, so I guess I don't want to hook too hard.
